Any thoughts on the FP TD05H 20g?

So what all would I need to put this turbo on my talon? My stock turbo just went out today. Can I bolt this turbo on with the exception of new coolent oil lines, and a j pipe? Is there other 20g's I could get besides the buscher one?

Have you paid attention to nothing that was said in this thread?

I am wondering if i should switch to the 7cm housing, i have the hahn 20g kit with the 10cm housing and lags like mad. i only run 20 psi and it does not full spool to about 4200RPM, then pulls like mad.
ported 2g manifold, spacer, T3 plate adapter, AVCR. Bought a cyclone manifold hoping it would help some but have not put it on yet.
 
I made an adapter plate today to install a holset 20 psi actuator. Much better boost control. Hits about 30, and holds about 28 to redline with my current setup, loads more fun.

In case anyone doesn't know. When you run more than about 25 psi, it will surge horribly below 4000 rpm's. I just make sure to not punch it below 4k.

Wouldn't tb/intake manifold/cams help this?
 
Fully built car, only thing i don't have on it is a smim. If i only run 20 psi it's ok. The 20g compressor just can't do 30+ psi on a 2 liter at 3500 rpm's.

Ahh gotcha. When I had a srt4 I had that issue - hopefully I won't run into to many problems with my 20g...it doesn't have the same compressor cover like that FP turbo does.
 
Here's a pic if it helps anyone. We ran an FP20g way back when, and I adapted a DSM style actuator to it by making an adaptor plate that bolted to the compressor housing. This allowed me to position it down low like the 14b/16g so the rod had the same pre-load and angle on the flapper arm. This setup worked flawlessly holding boost as high as 28psi to 7k and ran 11.0 @ 126. Putting the actuator low also allows more fan clearance.

^^^Nice as always Steven!

Let me guess. You had surge issues because you were running a stock td04h turbine wheel with something big on the other end :) . That's why you had surge with a 2.4 litre, right?

Yeahhhhhh that would be the one - that little turbo took a harsh beating though. I actually put the boost controller on my td05h 20g last night and stopped around 22psi - you can hear it surge just a tiny bit around 4k ish then it goes away.

I have 1 setting on my boost controller that only runs 15psi until 4000, then ramps it up to 23, feels like a na honda powerband. The other setting is a fully closed wastegate, i don't punch it until 4k with that setting, but it hits 32-35, and ends up holding about 28ish.
I've thought about running the 10cm t3 housing to get rid of the surge, and get some more top end power, but the turbine exit is smaller than a 6cm 14b housing. I don't think any porting could get it to have an exit the size of my evo housing.
 
That's kinda how it's been for me - I've been on wastegate pressure for the past week or so, so 10psi until it creeps to 20psi. However - I'm going to enjoy this turbo for a while as I've decided to go HX40/external gate - hopefully within the next 2 or 3 weeks I'll be on that setup. I still love this 20g though.

Throw some e85 in the tank, max it out, and learn to drive around the surge, it's a totally different experience. All 4 of my tires are bald now.ROFL
 
I've actually switched over to 100% e85 on the last tank, ran into the issue where there was still some 93oct in there - i'm about empty now, probably 2 gallons or so, I have to "go to walmart" today and hopefully it will be out of gas. Already got a 5 gallon container of e85 ready to go in :D

Sorry if this turns out to be a dumb statement or question, but here goes anyway. By 7cm housing are you talking about an Evo 3 16G housing? Am considering this 20G with a my Evo 3 16G housing but just wondering if the wastegate housing could be ported enoughl
 
Yea, we are referring to the evo3 7cm housing. The FP 20g is a TD05 wheel so it will bolt right into the housing.

I have a evo 7 cm housing on my 14b with an external gate off the o2 housing. I am pretty sure the evo 3 housing use a 34mm flapper door. That should be sufficient for your 20g, but you will have to modify how the waste gate sits since the compressor covers are different.

He is the port work on my housing. 16g in the picture, not the 14b I am running right now.

I'm very interested in this turbo and running it with a T3 mani, I would like to hear more about that since obviously it was the way the turbo was meant to be run IMO. What o2 housing is used with the T3 exhaust housing??

The t3 housing has a 3-bolt discharge flange, and will need a custom o2 housing. However, the outlet of the t3 housing is around 2", smaller than the outlet of a 6cm 14b housing.
 
Here's a pic if it helps anyone. We ran an FP20g way back when, and I adapted a DSM style actuator to it by making an adaptor plate that bolted to the compressor housing. This allowed me to position it down low like the 14b/16g so the rod had the same pre-load and angle on the flapper arm. This setup worked flawlessly holding boost as high as 28psi to 7k and ran 11.0 @ 126. Putting the actuator low also allows more fan clearance.

What turbine housing did you use on this 20g?
 
I run this turbo in a ported evo3 turbine housing and the only way I solved the wastgate issue was to get the map 38mm recirculated external wastegate. and even with this the turbo still surges under part throttle. And I would definitely try to find an 8cm turbine housing because I find it chokes out after about 22psi. because between 25 and 22 psi I am only flowing about 39-40lbs/min. and this is on a ported 2g manifold. so I suggest if you want the most out of this turbo get the
fp race manifold, 8cm turbine housing or a clipped turbine wheel, and cams.

so in the end I would NOT sugest this turbo even though the price is good because by the time you get done spending the money to make the turbo flow what it should up top you could have just spent the money on like fp68hta witch flows 47lbs/min on an uncliped turbine wheel only god knows what that little monster would do in an 8cm turbine housing. So the point is save your money a little longer and get a proven design like the 68hta. Just my personal opinion and 2cents. :thumb:

You will NOT see close to 47lb/min with the 68hta with stock cams either. . . You've just suggested a tubo you've never run, nor know what it takes to get that turbo to perform to the potential for which the builders have designed it.

I agree with your results. My 20g (pics posted earler) is showing 40lb/min too with a ported 2g manifold and 7cm^2 turbine housing. At only 25psi just like you and I have similar cams (I can't go any higher on pump gas with this intecooler), stock intake manifold and stock head ports. . . It's amazing that you and I are seeing such high flow at only 25psi with cams similar to hks 272s (you don't even need to swap out the stock valve springs). Goes to show that the 20g compressor wheel in the 17c compressor housing is a very nice setup! Efficiency is there to require less from the turbine section. Thus a good amount of exhaust is freely flowed out the exhaust via the wastegate.

Folks with the 68hta are getting similar results to us. The idea behind the fp68hta is to look stock or look like a 16g but actually get more flow out the tail pipe at the same spool speed. Difference is they can ramp up the boost to 30psi and still make hugh gains in flow. . . The 20g starts to choke with me too early in that relm when I put e85 in the tank and retuned.
